8. DUE DILIGENCE REVIEW.

8.1 Review By Buyer. Buyer shall have reasonable access to Seller’s records pertaining to the Assets and may conduct, at its sole cost, such title examination or investigation, and other examinations and investigations, as it may in its sole discretion choose to conduct with respect to the Assets in order to determine whether Defects (as below defined) exist. Should, as a result of such examinations and investigations, or otherwise, one or more matters come to Buyer’s attention which would constitute a Defect, Buyer shall promptly, but no later than two (2) days prior to Closing, notify Seller in writing (a “Notice”) of any Defects.

8.2 Nature of Defects. The term “Defect” as used in this Section shall mean the following; provided, however, that Permitted Encumbrances (as hereinafter defined) shall not constitute Defects:

(i) NRI or WI Variances. Seller’s ownership of the Assets is such that, with respect to a Well or any of the Leases listed on Exhibit A hereto, it (A) entitles Seller to receive a decimal share of the oil, gas and other hydrocarbons from all depths (or if depth limitations are noted on Exhibit A, from the depths specified), as shown on Exhibit A, which is less than the decimal share set forth on Exhibit A in connection with any such ▇▇▇▇▇ or lease in the column headed “Net Revenue Interest” or (B) causes Seller to be obligated to bear a decimal share of the cost of operation of any such ▇▇▇▇▇ or Lease greater than the decimal share set forth on Exhibit A in connection with any such ▇▇▇▇▇ or lease in the column headed “Working Interest”.

- 15 -

(ii) Liens. Seller’s ownership of an Asset is subject to a lien other than (A) a lien for taxes which are not yet delinquent or (B) a mechanic’s or materialmen’s lien (or other similar lien), or a lien under an operating agreement or similar agreement, to the extent the same relates to expenses incurred which are not yet delinquent or (C) liens which will be released at or before Closing.

(iii) Imperfections in Title. Seller’s ownership of an Asset is subject to an imperfection in title which, if asserted, would cause a Defect, as defined in subparagraph (i) above.

8.3 Permitted Encumbrances. As used in this Section 8, the term “Permitted Encumbrances” means:

8.3.1 lessor’s royalties, non-participating royalties, overriding royalties, division orders, sales and transportation contracts containing customary terms and provisions, reversionary interests, and similar burdens if the net cumulative effect of such burdens does not operate to reduce the net revenue interest in any Asset to an amount less than the net revenue interest set forth on Exhibit A, Schedule 1 or increase the working interest of any Asset from that set forth in Exhibit A, Schedule 1 without a corresponding increase in the net revenue interest;

8.3.2 subject to the provisions of Section 12.2 hereof, required non-governmental third party consents to assignments and similar agreements with respect to which prior to Closing (i) waivers or consents are obtained from the appropriate parties, or (ii) the appropriate time period for asserting such rights has expired without an exercise of such rights;

8.3.3 liens for taxes or assessments not yet due or delinquent or, if delinquent, that are being contested in good faith in the normal course of business;

8.3.4 all rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil and gas leases or interests therein, if the same are customarily obtained subsequent to such sale or conveyance and Buyer and Seller have no reason to believe they cannot be obtained;

8.3.5 easements, rights-of way, servitudes, permits, surface leases and other rights in respect of surface operations, provided they do not materially interfere with Buyer‘s operation or use of the Assets;

8.3.6 defects, irregularities and deficiencies in title of or to any rights-of-way, easements, surface leases or other rights which in the aggregate do not materially impair the use of such rights-of-way, easements, surface leases or other rights for the purpose for which such rights will be held by Buyer and would not have a material adverse effect on the operation or value of any of the Assets;

8.3.7 any lien, privilege or encumbrance covering the Assets to be released at or prior to Closing, which Seller has disclosed on Schedule E; and

- 16 -

8.3.8 preferential rights to purchase and required non-governmental third party consents to assignments and similar agreements with respect to which prior to Closing (i) waivers or consents are obtained from the appropriate parties, or (ii) the appropriate time period for asserting such rights has expired without an exercise of such rights.

8.4 Seller’s Response to Notices; Failure to Respond. Seller shall have one (1) day from receipt of a Notice to respond to any Notice timely delivered by Buyer pursuant to this Section 8. Such response must be in writing to be effective and may include an objection to the existence or amount of any claimed Defect or adjustment, or an election to cure any claimed Defect. Failure to so respond by Seller shall constitute a waiver of any rights to cure or object to Defects timely asserted by Buyer prior to the Notice Deadline. If Seller waives prior to Closing any rights to cure or object to a Defect, the Purchase Price shall be adjusted by the amount of such Defect claimed by Buyer in its Notice. There shall be no adjustments to the Purchase Price for Defects if the total adjustment is $500,000.00 or less in the aggregate, and then only to the extent of the excess over $500,000.00.

8.5 Election to Cure. If Seller elects to cure or objects to an asserted Defect, the Closing shall proceed if otherwise permitted by this Agreement and the Purchase Price shall be reduced by the amount of such Defect. If Seller elects to cure (in its response or after arbitration) an asserted Defect, Seller shall then have until 30 days after the Closing, or, if Seller disputes the asserted Defect and arbitration of such dispute occurs, 60 days after the arbitration proceedings set forth below are completed, to cure the underlying asserted Defect at its sole cost, risk and expense. The deadline for completing such cure may be extended by Buyer at its sole election if it is satisfied with the progress made by Seller. If by such date Seller can demonstrate to Buyer’s reasonable satisfaction that such asserted Defect has been cured, then Seller shall be entitled to payment in immediately available funds within ten business days of the date Seller demonstrates to Buyer’s reasonable satisfaction that such asserted Defect has been cured.

8.6 Arbitration. If Seller and Buyer cannot agree on whether an asserted Defect exists, or (before or after the Closing) whether an asserted Defect has been cured, or the amount of reduction in the Purchase Price for any Defect, then such issue shall be settled by arbitration in accordance with Section 14. If the aggregate Purchase Price reduction claimed by Buyer exceeds 10% of the Purchase Price and neither party has terminated this Agreement pursuant to Section 12.3, then the Closing will be postponed until the completion of the arbitration.

9. ENVIRONMENTAL MATTERS

9.1 Environmental Review. Promptly after signing this Agreement, Buyer may request access to the Assets (if operated by Seller) and the non-privileged environmental data in Seller‘s files for the Assets to be sold herein. Buyer may request Seller’s assistance in gaining access to Assets operated by others, but Buyer will be responsible for contacting the operators of such Assets to arrange for review and inspection, at Buyer’s sole cost, risk and expense. Buyer specifically acknowledges that any access to Seller-operated Assets or such Seller data is given as an accommodation only, at Buyer’s sole cost, risk and expense, that Seller makes no

- 17 -

representations whatsoever as to the accuracy, completeness, or reliability of any such environmental information so or otherwise disclosed to or obtained by Buyer and that Buyer relies and depends on and uses any and all such environmental information, review or inspection exclusively and entirely at its own risk and without any recourse to Seller whatsoever. Seller shall cooperate with Buyer for the performance by Buyer of any additional environmental testing at Buyer’s expense prior to Closing, which testing shall be conducted in a reasonable manner so as not to interfere with Seller’s or operator’s operation of the Assets, and Seller and Buyer shall cooperate to ensure that such testing is performed on an expedited and confidential basis before Closing. Results of any such tests shall be treated as confidential, except to the extent disclosure is required under applicable law.

9.2 Material Contamination. If as a result of information provided pursuant to Section 9.1, or any additional information which Buyer obtains from other sources, or any such testing done by Buyer, it is determined prior to Closing that the environment associated with the Assets has been materially contaminated (“Material Contamination” or “Alleged Material Contamination”, such terms being defined as the violation of Environmental Laws (as defined below) to the extent that as to each claim (i) prosecution, if instituted, would be reasonably likely to result in a penalty, fine or damage payment of $500,000.00 or more, or (ii) removal and remediation of such contamination required by Environmental Laws would be reasonably likely to result in expenditures of $500,000.00 or more), Buyer shall notify Seller in writing of any and all such Alleged Material Contamination claims no later than 4:00 p.m. CST, four (4) business days prior to Closing. Such notification shall include (i) a detailed description of such claims, (ii) a copy of any environmental assessment, reports, data and information pertaining to such claims, and (iii) Buyer’s calculation of the amount by which such claims have diminished the value of the Assets, which amount shall be determined by Buyer in good faith and in a commercially reasonable manner.

9.3 Remedies for Material Contamination. Either:

9.3.1 Prior to or at Closing, Seller and Buyer shall mutually agree in writing, separate and apart from this Agreement, that Seller shall correct or make arrangements for the correction of such Alleged Material Contamination, but only in an amount up to each claim, and that Closing shall proceed with Seller indemnifying Buyer against all Claims attributable to such Alleged Material Contamination and without reduction of the Purchase Price;

9.3.2 Buyer shall correct or make arrangements for the correction of such Alleged Material Contamination, after Closing, and the parties shall proceed to Closing with a reduction of the Purchase Price in an amount mutually agreed to by the parties and with Buyer defending, indemnifying and holding the Seller Parties harmless against all Claims attributable to such Alleged Material Contamination; or

9.3.3 Prior to or at Closing, Seller and Buyer shall mutually agree in writing separate and apart from this Agreement that Buyer shall accept the Assets subject to such Alleged Material Contamination, that the parties shall

- 18 -

proceed to Closing without adjustment of the Purchase Price, and that Seller shall indemnify Buyer against all Claims incurred by Buyer with respect to such Alleged Material Contamination up to but in no event to exceed ten percent (10%) of the initial unadjusted Purchase Price set forth in Section 2.1 and only as to that portion of such Claims which are in excess of $500,000.00 of the initial unadjusted Purchase Price set forth in Section 2.1 (such amounts being cumulative for any and all claims of Alleged Material Contamination made by Buyer).

If the parties are unable to agree upon one of the foregoing options, either party shall be entitled to terminate this Agreement without further liability to or for either party pursuant to the provisions of Section 12.3, unless Buyer agrees to waive such Alleged Material Contamination and assume all liability and obligations relating thereto. Each party shall cooperate with the other party’s reasonable corrective work, and any operations unreasonably interfering with the corrective work shall cease until correction is completed.

9.4 Indemnity Provisions. The indemnities provided for in this Section 9 by Buyer and Seller, as the case may be, for Claims shall include, without limitation, an agreement to protect, indemnify, hold harmless and defend the Buyer or Seller, as the case may be, and Buyer’s and Seller’s Parties, respectively, against any and all Claims, whether based on any theory of liability, including, but not limited to, negligence, tort, breach of contract (express or implied), breach of warranty (express or implied), strict liability, regulatory liability, or statutory liability, regardless of the sole, joint or concurrent negligence, strict liability, regulatory liability, statutory liability, breach of contract, breach of warranty, or other fault or responsibility of Buyer or Seller or any other person or party, arising under any obligations under this Agreement or imposed by any applicable statutes, laws, rules, regulations, or orders. The indemnities will further include an agreement by the party providing the indemnification to take whatever actions are necessary to protect the party being indemnified from being subjected to any such Claims, and to comply with reasonable requests by the party being indemnified to take such actions.

9.5 Post-Closing Environmental Indemnification by Buyer. As of the Closing, but subject to the provisions of Sections 9.3 and 9.6, Buyer specifically assumes and shall be responsible for all environmentally-related duties and obligations of Seller and Seller Parties with respect to the Assets from and after the Effective Date and shall protect, defend, indemnify and hold Seller and Seller Parties harmless from and against any and all Claims under any Environmental Law (hereafter defined) with respect to the Assets from and after the Effective Date, including with respect to any conditions and obligations existing as of the Effective Date or relating to periods before the Effective Date.

9.6 Exclusion from Buyer’s Indemnification. Anything in this Agreement to the contrary notwithstanding, it is agreed and understood that Buyer shall have no liability for, and Buyer’s post-Closing environmental indemnification of Seller shall not include any responsibility for disposal off-site from the Assets, that occurred at any time before the Closing, of hazardous substances, wastes, materials and products generated by or used by or used in connection with the Seller’s operation of the Assets.

9.7 CONDITION OF THE ASSETS AND SPECIFIC BUYER INDEMNIFICATION WITH RESPECT TO NORM AND OTHER HAZARDOUS SUBSTANCES: Buyer specifically assumes the risk of the condition of the Assets and shall inspect the Assets prior to Closing, or hereby expressly waives such right, if not exercised. Any such inspection, if made, shall cover but not be limited to the physical and environmental condition, both surface and subsurface, of the Assets. It is expressly recognized by Buyer that the lands and/or water bottoms, along with surface facilities and production equipment located thereon, having been used in connection with oil, gas, and water production, treatment, storage, and disposal activities, may contain Naturally Occurring Radioactive Materials (NORM), asbestos and other hazardous substances as a result of these operations. The generation, formation, or presence of NORM, asbestos or other hazardous substances in or on the Assets shall, after the Effective Date set forth herein, be the sole responsibility of Buyer and Buyer and all future assignees and successors of Buyer shall defend, indemnify and hold Seller and Seller Parties harmless from any and all Claims resulting from any and all claims, demands, losses, liabilities, liens, judgments, settlements, suits, causes of action, fines, penalties, fees (including, without limitation, attorneys fees and court costs), costs, and expenses (including, without limitation, expenses associated with investigation of claims, testing and assessment), whether based on any theory of negligence, tort, breach of contract, breach of warranty, strict liability, regulatory liability or statutory liability, regardless of the sole, joint or concurrent negligence, breach of contract, breach of warranty, strict liability, regulatory

- 20 -

liability, statutory liability, or other fault or responsibility of Seller or any other person or party, asserted or filed on or after the Effective Date in any way arising from, resulting from or related to the presence of NORM, asbestos or other hazardous substances whether such NORM, asbestos or other hazardous substance was in place before or after the Effective Date. Any conveyance, transfer or assignment of all or part of the Assets by Buyer, its successors or assigns in which the grantee, transferee or assignee fails to expressly assume this obligation shall be deemed null and void. Accordingly, lands and/or water bottoms, the ▇▇▇▇▇, and the Personal Property transferred herein are transferred with the restriction that they will be used only in connection with oil and gas producing activities associated with the Leases, and will not be subsequently transferred by Buyer or Buyer’s assignee for unrestricted use unless the concentrations of NORM, asbestos or other hazardous substances associated therewith are independently determined by a competent laboratory and are found below the levels specified as allowable for unrestricted transfer as set forth in any and all applicable laws, orders, rules or regulations of any governmental agency or court having jurisdiction. Additionally, Buyer agrees to comply with all provisions of such laws, orders, rules or regulations applicable to said lands and/or water bottoms, the ▇▇▇▇▇, and the Personal Property. Buyer further agrees to cause the provisions of this clause to be included in all subsequent sales or transfers of any interest in the Assets, and to cause all purchasers or transferees of the Assets to expressly acknowledge and assume all such obligations.

9.8 Waiver. Buyer waives for all purposes all objections associated with the environmental and physical and other condition of the Assets (including Material Contamination and Alleged Material Contamination), unless raised by proper notice within the applicable time period set forth in Section 9.2 and made Seller’s responsibility under Sections 9.3.1 or 9.3.3, and Buyer (and on behalf of Buyer Parties and their successors and assigns) irrevocably waives any and all claims, except Claims under Seller’s indemnities pursuant to Sections 9.3.1 and 9.3.3, they may have against Seller and Seller’s Parties associated with the same.

10. ADDITIONAL COVENANTS

10.1 Operations Prior to Closing. After the date of this Agreement and prior to the Closing, unless Seller and Buyer otherwise agree, Seller shall only enter into agreements or transactions in relation to the Assets which (i) individually involve a fair market value of less than Fifty Thousand United States dollars ($50,000.00), and (ii) are entered into in the ordinary course of business consistent with past practices. Seller shall not be obligated for any expenditures after the execution of this Agreement or the Effective Date, whichever is the earlier, and shall recover any charges and expenses as part of the Final Settlement Statement adjustments as appropriate. Such charges and expenses include, but are not limited to, those incurred pursuant to the authority for expenditures (“AFEs”) listed on Exhibit B hereto. In the event that an expenditure for purposes other than day-to-day operations or those pursuant to the AFEs is proposed or contemplated, Seller shall submit such proposal to Buyer for concurrence. Buyer will assume the risk of any consequences which arise as a result of Buyer’s failure or refusal to participate in or approve and pay such expenditure. Additionally, after the signing of this Agreement and prior to Closing,

- 21 -

Seller shall have the right to make any changes, repairs or modifications, or incur any expenditures deemed necessary by Seller to prevent or react to an emergency or environmental incident. With regard to the preceding sentence, Seller shall attempt to secure Buyer’s consent prior to any such expenditure or action, however, Seller shall have the right to cause or effect such expenditure or action with or without such approval, acting as would any prudent operator under similar circumstances. Unless Buyer and Seller otherwise agree, Seller shall not materially alter the Assets (other than the use of supplies and consumables) or remove any improvements, equipment or property which comprise the Assets (other than the use of supplies and consumables). Seller shall promptly notify Buyer of any material matter affecting the Assets known to Seller which arises from the date of this Agreement to the date of Closing.

10.2 Consents to Assign. Seller represents that the transfer by Seller of the Assets, or any portion thereof, are subject to the approval of lessors or governmental agencies having jurisdiction, or other forms of consent, and are subject to any rights of first refusal or preferential rights of purchase in favor of third parties. Seller shall, prior to Closing, use its reasonable efforts to attempt to obtain the necessary non-governmental approvals and consents to assign. If consents are denied or not acquired prior to Closing, the affected Assets shall be deleted from this Agreement and the Purchase Price decreased by the amount allocated by Buyer on Exhibit A, Schedule 1, with the remaining Assets to be sold hereunder.

10.3 Preferential Rights to Purchase.

10.3.1 Notice. Seller shall provide any required preferential right to purchase notifications and Buyer and Seller will collaborate on and make reasonable efforts to agree on the individual allocations prior to providing any notice to a third party holder of a preferential right to purchase.

10.3.2 Third Party Exercise. If a third party gives notice of its intent to exercise a preferential right to purchase any of the Assets, the affected Assets will not be sold to Buyer. Any preferential purchase right must be exercised subject to and on the same terms and conditions of this Agreement.

10.3.3 Third Party Failure to Purchase. If a third party gives notice of its intent to exercise a preferential right to purchase any of the Assets, but does not close the purchase for any reason either before or within a reasonable time after Closing, then there shall promptly be an additional Closing between Seller and Buyer for the Assets pursuant to the terms of this Agreement, by which Seller will transfer the Assets to Buyer and Buyer will promptly pay Seller the Purchase Price.

11. COVENANTS, ASSIGNMENTS AND CONTINUING OBLIGATIONS

11.1 It is the intent and effect of this Agreement that the conveyance, transfer or assignment of any Assets by Buyer or any future conveyances, transfers or assignments made by Buyer shall not in any way diminish, compromise, extinguish,

- 22 -

or effect a release of Seller’s rights against Buyer, or Buyer’s obligations to Seller. It is also the intent and effect of this Agreement that all conveyances, transfers or assignments of any Assets by Buyer and all future conveyances, transfers or assignments made by Buyer shall create rights in favor of Seller under this Agreement and under all subsequent conveyances, transfers or assignments pertaining to the Assets, and that the Seller is a third party beneficiary of such subsequent conveyances, transfers or assignments, so that the party or parties to whom Buyer conveys, transfers or assigns any Assets shall likewise be bound with Buyer to Seller for performance of Buyer’s obligations to Seller under this Agreement. Buyer specifically agrees and warrants that in the event of future conveyances, transfers or assignments of the Assets (in whole or in part) by Buyer, Buyer shall require that as part of the conveyances, transfers or assignments the party or parties to whom the Assets are conveyed, transferred or assigned shall agree to assume, be bound by and subject to all of Buyer’s obligations to Seller and shall fulfill those obligations. Buyer further agrees, understands and warrants that in the event of future conveyances, transfers or assignments of the Assets (in whole or in part) by Buyer, Buyer shall remain bound and subject to all of Buyer’s obligations to Seller and shall remain responsible for fulfilling those obligations even though Buyer has conveyed, transferred or assigned the Assets. Buyer further agrees, understands and warrants that all future assignments, conveyances or transfers of any Assets shall also be accompanied by the assignees’, grantees’ or transferees’ acceptance and full assumption of the obligations that Buyer owes to Seller. The obligations and responsibilities of Buyer to Seller, and of Buyer’s assignees, grantees or transferees to Seller, shall be joint and several and shall run with the Assets assigned, conveyed or transferred, so that all subsequent assignees, grantees and transferees also accept the same obligations to Seller, without Buyer or any assignees, grantees or transferees being released of any of their obligations to Seller. Such obligations shall include, but not be limited to, those involving abandonment obligations, covenants, terms, conditions, indemnities, liabilities, and assumed risks.

11.2 Delivery of Financial Documents.

11.2.1 Reserve Reports. Seller acknowledges that Buyer has been working with Netherland, ▇▇▇▇▇▇ & Associates, Inc. (the “Reserve Engineer”) in connection with the preparation for Buyer by the Reserve Engineer of a reserve and estimated present value determination with respect to the Assets as of December 31, 2010 of the type required by the SEC Requirements (as defined below), and to the extent applicable or required, accompanied by the consent of the Reserve Engineer to references to their firm and their report with respect to the Assets in any such document referred to in clauses (i) – (iii) of this paragraph. Seller does not object to, and will cooperate with, the preparation of such reserve report, including, without limitation, promptly providing the reserve information to Buyer and the Reserve Engineer and delivering to the Reserve Engineer customary representation letters reasonably requested by the Reserve Engineer. Buyer shall bear all reasonable out-of-pocket costs of the preparation of such reserve report.

11.2.2 The term “SEC Requirements” means Regulation S-X and Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”) and of

- 23 -

the type and form customarily included in (i) offering memoranda pursuant to 144A promulgated under the Securities Act, (ii) registration statements under the Securities Act and (iii) reports required to be filed under the Securities Exchange Act of 1934, in each case with such disclosures as are required by the Securities and Exchange Commission (the “SEC”).

11.2.3 Financial Statements.

a) Seller acknowledges that the SEC Requirements require Buyer to disclose (1) audited statements of revenue and direct operating expenses relating to the Assets for each of the years in the three year period ended December 31, 2008, 2009 and 2010, together with the report of an independent auditing firm thereon, and (2) unaudited statements of revenue and direct operating expenses relating to the Assets for each of the nine month periods ended September 30, 2010 and 2011, together with the report of an independent auditing firm thereon (collectively, the “Required Financial Statements”), in each case of the type required by the SEC Requirements.

As of Closing, the Seller’s balancing obligation or credit expressly represented on Exhibit D with respect to hydrocarbon imbalances as of the Effective Date shall transfer to Buyer. For purposes hereof, “Hydrocarbon Imbalances” are defined as (i) over-production or under-production with respect to oil or gas produced from or allocated to the Assets where Seller is out of balance with Buyer or with other working interest parties in the Assets; and (ii) any oil and gas imbalances existing on gathering or transportation agreements or any other circumstances where Buyer would be obligated by virtue of any pipeline imbalance, pipeline company operational flow order, prepayment, take-or-pay agreement or similar arrangement binding on the Assets after Closing to deliver gas produced from the Assets at some future time without then receiving full payment therefore. If Seller is a party to an oil or gas balancing agreement or other reconciliation obligations pursuant to any operating agreement covering all or

- 31 -

a portion of the Assets, Buyer shall assume all rights and duties of Seller pursuant thereto.

The Purchase Price shall be increased or decreased, as the case may be, as a result of imbalances owed to or by Seller as of the Effective Date.

After approval of the Final Settlement Statement, Seller thereafter shall have no further liability therefor nor benefit therefrom (whichever the case may be) for imbalances attributable to the Assets as of the Effective Date. If Seller is a party to a gas balancing agreement(s) or other reconciliation obligations pursuant to any commingling authority covering all or a portion of the Assets, Buyer shall assume all rights and duties of Seller pursuant thereto. If the Assets are not covered by a gas balancing agreement or other reconciliation obligations pursuant to any commingling authority, Buyer shall fulfill its obligations under this provision in accordance with applicable law. Buyer agrees to indemnify, defend and hold Seller and Seller Parties harmless against any and all losses, Claims, suits and liabilities arising directly or indirectly out of Buyer’s failure to fulfill its obligation under this provision.
